almost all POs start with 87. Speedy Pros are still in the 77/78s
That is true from ~2002 to 2019 but they have now snuck into the 79m region.

What had concerned me was the new watch I am planning to buy has a serial number almost 2000 numbers SMALLER than a used but identical model I saw online that was purchased in March of 2017. So, if the numbers reflect the chronological order in which they were manufactured, it means that the watch I am probably buying was made earlier than March of 2017. Therefore, it was sitting on the store's shelf for at least 3.5 years. When I questioned the AD, she said the numbers were randomly assigned and therefore I could not draw the conclusion I did. The salesman at the Omega Boutique confirmed what my AD said.
Well that is just sales bs. Omega serials have always been chronological within a model series. The question of whether they have moved over to a random serial model in the past couple of months is an interesting one and up for debate but certainly on a given model, the higher the serial the newer the watch* The new serials I am unsure about have a new format including letters. One I have seen was the form AXXXXXX

*There may be some variance here with models where movements are made in batches, particularly by a third party, I am thinking of vintage Speedmaster Pros for instance but in the main this holds true.

I just bought new Omega Speedmaster (Moonwatch) 1861 caliber from European (official dealer). The serial number starts with 788. According to Omega database it was produced between 2000-2006. Which means the watch was on the shelf for minimum 16 years. I asked European and they told the max time for selling Speedmaster from moment of receiving is about one week. I called Omega and they confirmed they are using random numbers now. Production date on the bottom of bigger box indicates July, 2020. I called the Omega again and they told the boxes produced prior to the watches in advance of many months. So that’s mean my watch approximate production date is end of 2020 or beginning of 2021.

By 788, do you mean 78,8xx,xxx? If so, the is perfectly normal for a Speedmaster (see above) and dates to maybe 2019-2021. Speedy dates are a bit weird though, I have seen one in the high 80m region recently. Read the thread. So far there is a discernible pattern in Omega serials, and yours fits the pattern.

Omega are definitely not producing sequentially numbered movements. I don't have any special knowledge here but going on what I've seen it doesn't look random, but grouped by production. Here's some example Speedmasters:
2014 Apollo XI Sedna 1861 is 7780xxxx
2015 DSoM Black 9300 is 8674xxxx
2015 Silver Snoopy 1861 is 8762xxxx
2018 Apollo XVII 1861 is 7875xxxx
2018 CK2998 1861 is 7880xxxx
2018 ST1 Ultraman 1861 is 7881xxxx
2019 DSoM Apollo 8 1869 is 7885xxxx
2019 Apollo XI Steel 3861 is 8641xxxx
2019 Apollo XI Gold 3861 is 8646xxxx
2020 Ed White 321 is 8880xxxx
2020 Silver Snoopy 3861 is 8316xxxx
2020 FOIS (~last produced) 1861 is 7890xxxx

I wonder what ever happened to Larry. He had a nice smile, even if he was a little overly concerned about serial numbers. 😀

Reviving this thread as there have been a couple of posts recently on the forum about modern Omega serial numbers and I'm keen to learn more. I'm trying to understand if there's some kind of system behind the numbering. Is it random? Is it chronological? Do the first two or three digits correspond to a particular model line?
I'm guessing it can't be entirely chronological as I have a Seamaster Pro 2551.80 purchased in 2005 that has a serial number starting with 808xxxxx and a Speedmaster FOIS purchased in 2019 which has the serial 788xxxxx. Can someone skool me?

I just bought a new moon watch from an AD last week. Because it's a 3861 movement on a regular ol' non-special-edition Speedmaster Pro, it must have been manufactured in 2021 is my understanding. My serial number is 83,3XX,XXX.

The alphanumeric serial numbers were announced (on the Omega Extranet) in November of 2019. In that announcement, there was no mention of the numbers no longer being sequential.

They did indicate that both numeric and alphanumeric serial numbers would be in production at the same time.

There must be a mix between sequential + random somewhere when they generate the serial number.

For example, my two METAS watches:

- No time to die: 831xxxxx
- Moonwatch 3861: 834xxxxx

While I saw in this forum, the conclusion about PO that uses 2500D have serial number starts with 8525xxxx. The 3861 movement was introduced in 2019, while PO with 2500D was stopped produced many years before 2019. If there is only sequential serial numbers, how could 3861 movement be produced even before a 2500D movement?

Read back. Different models of Omega eg Seamaster 300m and Speedmaster Moonwatch have always run chronologically in different serial ranges. It seems the 3861s are now in the 80m range but I still see nothing to suggest no pattern. While the 2500Ds sat in the 85m range, Moonwatches were sitting at 77-78m. In general for 2 examples of the same model, the lower serial is the older watch.

........................still not sold after 8 years........................

There's a good reason for that.

I do.

Like you can see, my 8800 has the 831xxxxx serial, the 3861 sapphire sandwich has 834xxxxx. But at the same time, I saw a seller here in Vietnam selling a 3861 hesalite with serial 829xxxxx.

So why the 8800 falls in between two 3861?

My third gen SMPc (non-wave dial) with the 2500D cal. starts with a 89 serial. I emailed Omega in 2020 and asked when it was made. Their reply was that it was made in 2011. This model began selling in 2012. So, no idea how this serial is from a year prior.
